SSA Heat Transfer Plus

Which part of the diagram shows convection?

• A

• B

• C

• D

How is the transfer of energy labeled in A different from the action labeled in C?

• The action in A shows heat transfer through radiation, while the action in C shows heat transfer from conduction.

• The action in A shows heat transfer from conduction, while the action in C shows heat transfer from radiation.

• The action in A shows heat transfer from radiation, while the action in C shows heat transfer from convection.

• The action in A shows heat transfer from convection, while the action in C shows heat transfer from the radiation.

How does the energy from the Sun contribute to the production of winds on the Earth?

• Different areas absorb the heat differently, so warmer air rises and cooler air moves in to fill the gap

• The Sun’s energy comes in radiating waves, which move the atmosphere around as they go through it

• Gravity pulls the air down from the tops of the mountains to the valleys and oceans, and this pushes on the air below

• Oceans heat and cool faster than the land, so they affect the air above them more than the land does

Joanne has been told that over time, the energy Earth radiates out into space is equal to the energy that Earth receives from the Sun. She is not sure whether this is true. Which concept below gives her the correct explanation?

• Earth loses less energy to space than it gains from the Sun because some of the energy it receives is consumed by Earth’s organisms

• We have not yet been able to accurately measure how much energy the Earth radiates into space, so we cannot answer this question

• Earth must lose an amount of energy equal to the amount it receives from the Sun, or the planet would become too hot for life to exist

• Earth cannot radiate energy into space because space does not have any atmosphere for the energy to travel through

The currents in Earth's mantle are responsible for a variety of observations of the way Earth's surface behaves. Which observation can most likely be explained by these cycling patterns?

• the mineral composition of bedrock

• the course of flow in the hydrosphere

• movement of Earth's crust

• the weathering of all mountains

What is the movement of material in Earth’s mantle most similar to in the atmosphere of the planet?

• the movement of air from areas of high pressure to low

• the precipitation from clouds where the density has become too high

• the radiation of the Sun causing bodies of air to rise

• he formation of clouds when temperature drops at high elevation

Which of the following is the least likely to cause heating of the air immediately above it

• lake

• city

• forest

• desert

 Jenny thinks that clouds make the air temperature cooler because in summer, a cloud-covered day is usually cooler than a sunny day. Joshua disagrees, saying that clouds really make the air temperature go up because it is the clear winter nights that are frosty, not the cloudy ones. Who is right, Jenny or Joshua?

• They are both wrong because the temperature of the atmosphere depends on radiation from the Sun and clouds have no effect on it

• Jenny is right because the clouds can’t conduct sunlight to the air below, and nights are expected to be colder anyway

• Joshua is right because the convection currents in the clouds keep the air moving and the temperature stays high as a result

• Both of them are right; at night the clouds cut down the heat radiation into space, and during the day they interfere with the radiation from  the Sun
